Festo
8191808
Ball valve unit VZBA-A-2-GG-63-T-22-F0507-V4V4T-PA60
The Festo 8191808 is a pneumatic 2-way ball valve featuring a quarter turn actuator and a soft sealing principle for in-line installation in any mounting position with an Rp2 fitting connection. Designed for a nominal width DN of 50 and a nominal pressure PN of 63, this 2/2 valve functions with a reversible flow direction, a flow rate Kv of 275 m³/h, and a breakaway torque of 44 Nm at nominal fitting pressure. It operates at a pressure range of 0.55 MPa to 0.8 MPa (5.5 bar to 8 bar, 79.75 psi to 116 psi) and accommodates a medium temperature of -10 °C to 200 °C across compressed air, inert gas, water without water vapor, and neutral liquids.

Request a QuoteWhy no listed price?
Industrial and obsolete parts are priced per enquiry: the final price depends on available stock, condition, quantity, and your delivery destination, so a fixed list price would be misleading. Request a quote and we confirm current pricing, lead time, and sourcing options — including hard-to-find and discontinued Festo references — within one business day.
